Question

however, when grown in soil with different concentrations of salt, individuals of this population show variation in their flowering time. which of the following statements is best supported by the information provided in the passage? choose 1 answer: a a single genotype can result in different phenotypes, depending on conditions in the organisms environment. b exposure to salt can affect whether an organism will have a certain set of alleles. c an individuals phenotype is determined only by the specific alleles they inherit.

Explanation:

• Option A: The passage states that the same population (implying same genotype set in general) shows different flowering times (phenotype) in different salt - concentration soils (environment). This matches the idea that a single genotype can lead to different phenotypes based on the environment.
• Option B: Alleles are genetic and not changed by salt exposure. Salt affects the expression of genes, not the alleles themselves. So this option is incorrect.
• Option C: The passage shows that the environment (salt concentration) affects the phenotype (flowering time), so phenotype is not only determined by inherited alleles. This option is incorrect.

Answer:

A. A single genotype can result in different phenotypes, depending on conditions in the organism’s environment.
